SELF-CLOSING CLOSET-VALVE.

SPECIFICATION forming part of Letters Patent No. 642,707, dated February 6, 1900. Application filed November 9,1899. Serial N0. 736,388. (No model.)

To aZZ whom it may concern.-

Be it known that I, HORACE FALK NEU- MEYER, a citizen of the United States, residing at Macungie, in the county of Lehigh and State of Pennsylvania, have invented a new and useful Self-Closing Oloset-Valve,of which the following is a specification.

This invention relates to self-closing closetvalves adapted to be operated by the downward pressure of a seat to open the same; and the object in view is to improve the construction and operation of devices of this character and give the valve a positive movement to open the supply and shut off the waste, and the return movement to close the supply and open the waste, and also to regulate the quantity of water that is let into and passes through the improved device and have the valve-stem work as a piston and constructed to provide water-packin gs to form a Vacuum and retard its upward movement, and thereby prevent water-hammer.

An advantage of the present construction is the facility with which the parts can be separated for the purpose of repair and also the ease with which it can be applied in operative position and also structurally organized to prevent freezing.

With the foregoing and other objects and advantages in view the invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of the improved device shown applied in operative position. Fig. 2 is a longitudinal vertical section of the improved valve. Fig. 3 is a transverse vertical section of the valve, showing the stem broken away. Fig. 4 is a detail perspective view of the valve controlling the inlet of water. Fig. 5 is a detail perspective view of the valve-stem.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The improved device comprises a body 1, having opposite horizontal branches 2 and 3, respectively, for the attachment of inlet and outlet pipes 4 and 5. The said body 1 also has a vertical neck 6 and a lower diametrically opposite tubular standard 7 which contains a lower chamber 8, and rises from a base-support 9, adapted to be secured in fixed position adjacent the closet or bowl. The bores of the neck 6 and standard 7 areof the same diameter and centrally interrupted by a valve-chamber 10, with which the branches 2 and 3 also communicate and provide means for the proper disposition and operation of a valve, which will be more fully hereinafter described. Communicating with the upper portion of the chamber 10, or rather with a point above said chamber, is a waste-pipe 11, which is connected up to a neck 12 of smaller form and integrally arranged in a plane at right angles to the neck 6, the said wastepipe being held to the necks 12 by a cup-nut 13, and from its connection the said wastepipe may extend away to any suitable point, such as to the soil-pipe of the bowl, with which the latter may connect. The wastepipe 11 communicates with the body 1 in a plane at'right angles to the direction of the inlet and discharge, and within the neck 6 and tubular standard 7 a stem 14 has movement and works as a piston, the upper extremity of said stem being screw-threaded, as at 15, to receive an adjusting-nut 16 and a lock-nut 17. A rod 18, having bearing against the under portion of a seat 19, is connected in an adjustable manner, by means of a coupling 20, with the upper screw-threaded extremity of the valve-stem 14, and when the proper adjustment has been acquired the coupling is locked against movement by the lock-nut 17, which is run up against the same. Between the nut 16 and the upper terminal of the neck 6 and surrounding the valve-stem 14 is a coiled spring 21, which operates to return the valve-stem to its normal position, the tension of said spring being regulable by the adjustment of the nut 16.

The stem 14 is supplied with a leather cupwasher 22 to operate in connection with the waste-outlet through the neck 12, and also has lower grooved water -packings 23, to thus adapt the lower part of the stem to act as a piston in the standard 7 and form a vacuum in view of the chamber 8 in relative connection with the bore of the standard, and thereby retard the upward movement of the valvestem and prevent what is known as waterhammer.

The inlet-pipe 4has its connecting extremity 24 enlarged to form a valve-chamber, and therein is seated a conical spiral spring 25, which engages the short stem 26 of a valveplunger 27, working horizontally into the valve-stem through the branch 2 and comprising a rubber valve 28, preferably of conical form, and a nut 29 for fastening the same. This plunger also includes angularly-disposed intersecting guides 30 and 31, which loosely fit within the bore of the branch 2 and hold the plunger in proper operative position relatively to the valve-stem, the guide 31 being longer than the guide 30 and havingan inner beveled end The projected end of the guide 31 normally rests on a shoulder 33 formed in the stem 14, and from which the wall of a cam-slot 34 extends outwardly and upwardly in a curved plane. Adjacent the cam-slot 34 the stem 14 has a groove 35 cut vertically therein and continuous with a slightly-deflected lower enlargement 36, the said groove 35 being adapted to communicate or be brought opposite the waste outlet or opening of the neck 12, and the enlargement 36 remains in communication with the valvechamber 10 to thereby permit a portion of the waste water to escape or be run out through the waste-pipe 11 and overcome the annoyance and inconvenience arising from freezing of water deposit within the body of the valve.

In the primary arrangement of the several parts and after having connected the inlet, outlet, and waste, the rod 18 coming down from the seat is cut to such a length as to allow the valve to open full. This full opening will adapt the device to low pressure, and where a higher or very high pressure is prevalent the nut 17 is loosened and the rod 18 and coupling 20 are moved downwardly to shorten the action of the valve-stem, and consequently the valve will not open so far, and hence the quantity of water passing into and through the valve can be easily regulated.

In the operation of the device the downward movement of the valve-stem will cause the washer 22 to come opposite the wasteoutlet through the neck 12 and close the same before the valve 28 or plunger of which .it forms a part is moved, and as a consequence there willbe no waste at all even on a high pressure or if the valve is only the least open. This is due to the fact that the cam-slot 34 is so constructed that the outwardly and upwardly inclined curved wall thereof has a short play before it strikes the beveled end 33 of the guide 31, and until a force is brought to bear on the said projected guide, which is sufficiently strong to overcome the action of the spring 25, which always tends to hold the valve 28 in closed position, said valve will remain in the outerportion of the bore of the branch 2. When, however, the stem 14 is depressed low enough the wall of the cam-slot 34 will strike or contact with the bevel 32 of the guide 31 and overcome the resistance of the said spring and force the valve 28 open, and thereby permit the water to pass into the outlet-pipe 5 and through the latter to the bowl of the closet. After pressure is removed from the seat 19 the spring 21 will exert its resilient effort against the nut 16, and thus gradually elevate the stem 14 in view of the formation of a vacuum, as heretofore explained, and ultimately allow the plungervalve 28 to seat itself and close the inlet-pipe. After the water has ceased to run into the inlet-pipe the valve-stem will continue to rise and until the cup-washer 22 has passed the waste-outlet in the neck 12. The water now remaining in the discharge pipe or outlet 5 will run back into the chamber 10 and enter the enlargement 36 in communication with the groove and escape through the wastepipe.

In disconnecting the parts for repairs it is unnecessary to remove the valve from its foundation or place of securement, and the plunger-valve 28 may be easilyregulated as to its sensitiveness by adjusting the cap-nut 37, and at times extra packings may be interposed between these parts. The exterior surface of the standard 7 may be suitably ornamented to break the continuity or sameness of said surface, and itwill be understood that the construction or function of the improved device does not demand a particular construction of closet or bowl and is equally well useful with any form of such device.

Changes in the form, proportions,and minor details may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
